My wife decided to buy gas for her 99 durango and when she go to start it, it would start then cutoff. She panic and waited about 15min then the car started. She drove it home shut it off and started again with no problem. Again I started the car no problem and drove for about 40 min then I turned it off and the same problem happened. What can be the problem I'm sorry its my wife Durango and not my expo.
